Lightweight typescript library for cross-chain wallets. Connect with multiple blockchains via a common interface, with support for the minimum features necessary.

XChainJS

XChainJS is a library with a common interface for multiple blockchains, built for simple and fast integration for wallets and more.

Interface

The interface is defined here.

Common Interface

The interface supports as a minimum the following functions for each blockchain:

1. Initialise with a valid BIP39 phrase and specified network (testnet/mainnet)
2. Get the address, with support for BIP44 path derivations (default is Index 0)
3. Get the balance (UTXO or account-based)
4. Get transaction history for that address
5. Make a simple transfer
6. Get blockchain fee information (standard, fast, fastest)

Extended Interface

Some blockchains have different functions. More advanced logic can be built by extending the interface, such as for Binance Chain and Cosmos chains.

Return the Client

For wallets that need even more flexibility (smart contract blockchains) the client can be retrieved and the wallet is then free to handle directly.

XChainJS uses following libraries, frameworks and more:

• BitcoinJS
• @binance-chain/javascript-sdk
• @ethersproject
• cosmos-client
• PolkadotJS
